Carlos Santana performing live at the O2, London, England - 22.06.08

The guitar great insists he was carrying so much anger and resentment around with him from his childhood that it "infected" him and his every breath.

He tells Rolling Stone magazine, "I was able to remove the anger by forgiving that man and ever since I did that, my breath doesn't smell like I need to have a breath mint or something. It changed my molecular structure.

"Before, you'd brush your teeth but still smell like anger."
